Went to airshow with my family on Saturday. I picked up two 750 passes from the Canara bank ticket counter. But I was quite disappointed when they did it allow me to the Exhibition hall since they don’t allow children below 15. This was not at all informed when I picked the tickets. To my enquiry they actually said kids doesn’t require tickets. I spoke to the organizer he said its business pass they have given to me. He advised parents can go one by one . What’s fun I don’t know. I think organizers purposefully hid this information at the ticket counter, If knew this before I would have just picked only 300 pass.
They had arranged buses to drop from the car parking slot in the morning but to my agony, they were few buses to drop back. We had to walk.

From where did you get that figure of 9G?
Theoretically, it is not possible for a human to execute such a high G turn and sustain in flight.
As per aero medicine, G forces above 7 G will make the pilot black out.
Most modern fighter aircrafts have 'fly by wire' technology in which if the pilot executes a high G maneuver beyond 6.5 Gs, the aircraft automatically takes over controls and resume straight and level flight.
This feature is required in a fighter aircraft as a safety measure as in many tail chases, the pilot unknowingly exceeds his G tolerance limits.

Actually, the aircraft powers up to go into a vertical Charlie because it would need that much more power to sustain forward flight at high angle of attack of the blades and not stall too

nahin yaar madmax it must be useful while overtaking other helicopters. afterall it is an indian chopper.

besides this thing can fly in reverse so useful then as well.

The rear view mirrors on fighter aircraft are used for tactical reasons as mentioned by MADMAX111. However, though the ORVM of ALH might be placed for similar reasons, it is mainly used to see the engine exhaust for fire during engine starts

Dude, if you quote a 6 year old post how will I remember where I got that from.

It must have been the commentator saying all that. After 6 years I don't really remember.

Sorry. I was not pointing a finger at you. My intention was to share the truth that 9G turn is difficult to believe and execute.
Please don't get me wrong.

Well, since we are revisiting an old thread let me add some: Modern fighter pilots are trained to withstand sustained 9G easily. Well, not easily, it takes a lot of training and special equipment (G-suit). But even F16 pilots, have been pulling those sort of G's since 1976! The electronics you refer too, have much higher G-loading limits.

Pilots can pull even higher G numbers for shorter times. Its the combination of G and the time exposed to it that determines whether you conk out.

Here is a good article on G in general and some specifics on human and what they can withstand, note there is positive and negative Gs with very different limits too:

As Jeroen mentioned, regular fighter pilots can handle 9G turns, with the G-suit. EADS is developing/has developed an even better G-suit that will help Typhoon pilots push 9.5G-10G. Some fighters themselves, since the 1970's designs, have 12G design limits if not more , though it does vary with flight and load conditions. Most jets will not do the full design limit at full load, maybe limited to 6 or 7G, but some like the F-16 are designed to sustain 9G with full internal fuel + normal air-air load (2-4 missiles). As for air-air missiles, they can pull in excess of 20Gs among the modern missiles.
